.SH "DESCRIPTION"
.PP
\fBmariadb-slap\fR
is a diagnostic program designed to emulate client load for a MariaDB server and to report the timing of each stage\&. It works as if multiple clients are accessing the server\&.
.PP
Invoke
\fBmariadb-slap\fR
like this:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmariadb-slap [\fR\fB\fIoptions\fR\fR\fB]\fR
.fi
.if n \{\
.RE
.\}
.PP
Some options such as
\fB\-\-create\fR
or
\fB\-\-query\fR
enable you to specify a string containing an SQL statement or a file containing statements\&. If you specify a file, by default it must contain one statement per line\&. (That is, the implicit statement delimiter is the newline character\&.) Use the
\fB\-\-delimiter\fR
option to specify a different delimiter, which enables you to specify statements that span multiple lines or place multiple statements on a single line\&. You cannot include comments in a file;
\fBmariadb-slap\fR
does not understand them\&.
.PP
\fBmariadb-slap\fR
runs in three stages:
.sp
.RS 4
.ie n \{\
\h'-04' 1.\h'+01'\c
.\}
.el \{\
.sp -1
.IP "  1." 4.2
.\}
Create schema, table, and optionally any stored programs or data you want to using for the test\&. This stage uses a single client connection\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04' 2.\h'+01'\c
.\}
.el \{\
.sp -1
.IP "  2." 4.2
.\}
Run the load test\&. This stage can use many client connections\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04' 3.\h'+01'\c
.\}
.el \{\
.sp -1
.IP "  3." 4.2
.\}
Clean up (disconnect, drop table if specified)\&. This stage uses a single client connection\&.
.RE
.PP
Examples:
.PP
Supply your own create and query SQL statements, with 50 clients querying and 200 selects for each:
.sp
.if n \{\
.RS 4
.\}
.nf
mariadb-slap \-\-delimiter=";" \e
  \-\-create="CREATE TABLE a (b int);INSERT INTO a VALUES (23)" \e
  \-\-query="SELECT * FROM a" \-\-concurrency=50 \-\-iterations=200
.fi
.if n \{\
.RE
.\}
.PP
Let
\fBmariadb-slap\fR
build the query SQL statement with a table of two
INT
columns and three
VARCHAR
columns\&. Use five clients querying 20 times each\&. Do not create the table or insert the data (that is, use the previous test's schema and data):
.sp
.if n \{\
.RS 4
.\}
.nf
mariadb-slap \-\-concurrency=5 \-\-iterations=20 \e
  \-\-number\-int\-cols=2 \-\-number\-char\-cols=3 \e
  \-\-auto\-generate\-sql
.fi
.if n \{\
.RE
.\}
.PP
Tell the program to load the create, insert, and query SQL statements from the specified files, where the create\&.sql
file has multiple table creation statements delimited by ';' and multiple insert statements delimited by ';'\&. The
\fB\-\-query\fR
file will have multiple queries delimited by ';'\&. Run all the load statements,
then run all the queries in the query file with five clients (five times each):
.sp
.if n \{\
.RS 4
.\}
.nf
mariadb-slap \-\-concurrency=5 \e
  \-\-iterations=5 \-\-query=query\&.sql \-\-create=create\&.sql \e
